Square-Enix is definitely no stranger to censorship, for example they censored the cross that appears when Fairy Heal is cast in the PSP ports of Star Ocean 1 and 2, and Kingdom Hearts II was full of censorship particularly in the Pirates of the Caribbean world.

^Interesting. I never knew those were censored... at best I've read/heard about censored stuff for FFVI for GBA (some re-censored sprites from the SNES version I think), Drakengard 1 (translations shenanigans) and Nier (also translations shenanigans IIRC).
